Abstract
A semiconductor device includes a semiconductor substrate. The semiconductor device includes a first fin protruding from the semiconductor substrate and extending along a first direction. The semiconductor device includes a second fin protruding from the semiconductor substrate and extending along the first direction. A first epitaxial source/drain region coupled to the first fin and a second epitaxial source/drain region coupled to the second fin are laterally spaced apart from each other by an air void.
